    13. 13. ARIADNE Repository Software Open Standards & Specifications SQI - PLQL - SPI - OAI-PMH - RSS - CAM Easy accessible API for search Metadata schema support IEEE LTSC LOM by default Any schema with an xml binding Open-source license Out-of-the-box deployment 9
    14. 14. Validation Service Manual check is very time consuming Tool for enforcing an validation scheme A set of validation rules Based on XSD Schema & Schematron Rules 10
    15. 15. Online Validation Paste metadata record http://bit.ly/90va7d e.g LOM instance Select validation scheme uri e.g http://ltsc.ieee.org/xsd/LOM/strict Validate & Consult Validation Errors Batch Validation 11
    16. 16. Transform MD MD Different Application Profiles e.g ARIADNE AP to CGIAR AP Different Metadata Schemes e.g DC to IEEE LOM Third-party Metadata to IEEE LOM 12
